Wild West settlements have a distinctive naming style and it can be quite hard to come up with a good one - let alone a whole string of them - that is going to fit in with the Dodge Cities and Rock Ridges familiar to your group from history and the screen alike.
So try this list for size. Some are real ones, some just sound right - Liberty, Fool's Gulch or Last Chance.
Roll, or read through them, as you design your map or find yourself being asked where the stage or railroad is going next, and you won't find yourself breaking the alternate reality by coming up with an inappropriate name like Crewe! You may even find yourself coming up with the story behind the name: Muleshoe or Bad Creek no doubt have a tale or two to tell about their foundation.
Another darn useful listing, pard'ner.
